REFRIGERATOR.

SPECIFICATION forming part of Letters Patent No. 477,803, dated June 28, 1892.

Application filed October 26, 1891. Serial No. 409,764. (No model.)

To all whom it may concern.-

Be it known that I, VALENTINE HOERSCHEL- MANN, a citizen of the United States, and a resithe improvements being more especially designed for preventing the formation of frost on the walls of the ice-chamber and the drip connected therewith, so that the entire refrigerator can be kept dry and the temperature in the same be readily regulated; and the invention consists of a refrigerator for butchers use in which the inner wall of the icechamber is provided with auxiliary walls that form air-spaces, so that the formation of ice on the walls of the ice-chamber isprevented as well as the drip produced by the melting of the frost when the temperature rises in the provision-chamber. At the lower part of the ice-chamber is arranged, in front of the outletopening for the cold air, a removable gate, provided with sliding registers, by which the supply of cold airto the refrigerating chamber is controlled.

In the accompanying drawings, Figures 1 and 2 represent vertical transverse sections of my improved refrigerator for butchers use, drawn, respectively, on lines 1 l and 2 2, Fig. 3. Fig. 3 is a horizontal sectionon line 3 3, Fig. 1, and Fig. 4.- is a vertical transverse section on line 4 4, Fig. 1, taken at right angles to the sections shown in Figs. 1 and 2.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents a refrigerator or a refrigerator-building, which is intended for the preservation of meat or other perishable substances. At one end of the refrigerating structure A is arranged an ice-chamber B, which is provided with an interior lining 9f sheet metal and a drip-pan C, which is located below the open grate-like bottom O of the ice-chamber. On the gratelike bottom 0 is placed the ice, which is mixed with rock-salt.

To prevent the formation of frost on the outer surface of the inner Wall of the icechamber B, owing to the low temperature pro duced by the ice and salt mixture, two auxiliary walls D D, of sheet metahare used in connection with said wall, as shown in Figs. 3 and 4. The Walls DD are preferably made of gates that are hinged to the side walls of the refrigerator A and connected at the center by a catch or other locking device 01, as shown in Figs. 1 and 3, so as to be parallel with the wall of the ice-chamber. The auxiliary walls D form with each other and the wall of the ice-chamber two air-chambers that prevent the formation of frost on the surface of the ice-chamber, so that the consequent drip produced by the melting of this layer of frost when the temperature in the refrigerator rises and the consequent annoyances attendant thereon are obviated. The auxiliary walls D D are not extended to the bottom of the refrigerator, but only so far as to leave an opening of sufficient size for the exit of the chilled air which passes through the gate at the bottom of the ice-chamber into the provision-chamber.

To regulate the supply of chilledair to the provision-chamber a transverse detachable section or gate D is used, which is provided with openings 6 and sliding registers c, by which latter the quantity of chilled air that passes from the ice-chamber to the provisionchamber is regulated. The height of the gate D is slightly larger than the outlet-opening for the chilled air at the lower part of the icechamber. The gate D is guided in suitable ways f, attached to the side walls of the refrigerator, so as to be removable whenever it should be required either for cleaning the air spaces formed by the auxiliary walls or layers D D or whenever a very low temperature is to be sustained in the provision-chamber, so that the entire body'of air chilled by the icechamber can be passed into the provisionchamber.

Having thus described-my invention, I'

claim as new and desire to secure by Letters Patent 1. In a refrigerator for butchers and others use, the combination, with an ice-chamber having a grate-like bottom and auxiliary walls arranged parallel with the wall of the ice-chamber, extending somewhat below the detachable gate in front of the air-opening i at the lower part of the ice-chamber, said gate being provided with openings and registers for the escape of the chilled air, substantially as set forth.

In testimony that I claim the foregoing as 'myinvention I have signed my name in presence of two subscribing witnesses.
